I have no friends at all. It’s like I’m a ghost in a world that has no place for me.

I am recently divorced and genuinely have no friends. It’s not that I don’t want any, I want friends, I want people to hang around with, I want connections and someone to talk to. It’s just that it feels like every person I know has some kind of major social circle that I’m not a part of. Many of my coworkers are a little standoffish, my friend group’s drifted apart and I’m not invited to many things when they get together. I’ve tried inviting people out for a drink and it seems like I’m calling them out of the blue and they have no idea how to react. Everything always seems so awkward when I try to connect with someone. Like I’m an outsider or something. I’m wondering if this is just me?
